ることを特徴とするデイスク保持装置。 It has a mounting plate made of a magnetic material, and a support foil that rotates around a spindle faces the mounting plate. A magnet with multi-pole magnetization in the circumferential direction is fixed to the upper and lower surfaces of the support foil, and a magnet is attached to the outer periphery of this magnet. A disk holding device characterized in that a ring-shaped member made of a non-magnetic material is fixed, and when the disk is mounted, the disk is clamped by a presser plate made of a magnetic material and fixed by adsorption to the magnet.
